  • Out of memory error while uploading file into a blob

    - by stacker
    I received a out of memory error SQL Error: 0, SQLState: 53200 from postgres while trying to upload a 10MB file into a single row with a column of blob-type bytea. Which configuration parameters should be changed to allow inserts of this size, or should this work out of the box without modifications? Is there an option like in informix-db to create so called blob-spaces?

  • Squid Log Rotation and Sarg

    - by beakersoft
    We have just setup squid as our proxy, and i was going to use Sarg to analyze the log files. I had initially set the Squid logs to rotate everyday so they dont get huge. The problem is i cant see an option in the squid config to read a folder full of squid log files (say *.log). Is there an easy way to do this or am i going to have to write a bash script or something to process them all into one before i get squid to read it? Cheers Luke

  • Linux - quota per directory?

    - by depesz
    I have following scenarios: Single partition mounted as /, with lots of disk space. There is a range of directories (/pg/tbs1, /pg/tbs2, /pg/tbs3 and so on), and I would like to limit total size of these directories. One option is to make some big files, and then mkfs them, and mount over loopback, and then set quota, but this makes expansion a bit problematic. Is there any other way to make the quota work per directory?

  • How to jump to a particular flag in a Unix manpage?

    - by dotancohen
    When reading a Unix manpage in the terminal, how can I jump easily to the description of a particular flag? For instance, I need to know the meaning of the -o flag for mount. I run man mount and want to jump to the place where -o is described. Currently, I search /-o however that option is mentioned in several places before the section that actually describes it, so I must jump around quite a bit. Thanks.

  • What the best way to achieve RPO of zero and lowest possible RTO (less than 15 minutes) with SQL 2008 R2?

    - by Adrian Hope-Bailie
    We are running a payments (EFT transaction processing) application which is processing high volumes of transactions 24/7 and are currently investigating a better way of doing DB replication to our disaster recovery site. Our current and previous strategies have included using both DoubleTake and Redgate to replicate data to a warm stand-by. DoubleTake is the supported solution from the payments software vendor however their (DoubleTake's) support in South Africa is very poor. We had a few issues and simply couldn't ever resolve them so we had to give up on DoubleTake. We have been using Redgate to manually read the data from the primary site (via queries) and write to the DR site but this is: A bad solution Getting the software vendor hot and bothered whenever we have support issues as it has a tendency to interfere with the payment application which is very DB intensive. We recently upgraded the whole system to run on SQL 2008 R2 Enterprise which means we should probably be looking at using some of the built-in replication features. The server has 2 fairly large databases with a mixture of tables containing highly volatile transactional data and pretty static configuration data. Replication would be done over a WAN link to a separate physical site and needs to achieve the following objectives. RPO: Zero loss - This is transactional data with financial impact so we can't lose anything. RTO: Tending to zero - The business depends on our ability to process transactions every minute we are down we are losing money I have looked at a few of the other questions/answers but none meet our case exactly: SQL Server 2008 failover strategy - Log shipping or replication? How to achieve the following RTO & RPO with logshipping only using SQL Server? What is the best of two approaches to achieve DB Replication? My current thinking is that we should use mirroring but I am concerned that for RPO:0 we will need to do delayed commits and this could impact the performance of the primary DB which is not an option. Our current DR process is to: Stop incoming traffic to the primary site and allow all in-flight transaction to complete. Allow the replication to DR to complete. Change network routing to route to DR site. Start all applications and services on the secondary site (Ideally we can change this to a warmer stand-by whereby the applications are already running but not processing any transactions). In other words the DR database needs to, as quickly as possible, catch up with primary and be ready for processing as the new primary. We would then need to be able to reverse this when we are ready to switch back. Is there a better option than mirroring (should we be doing log-shipping too) and can anyone suggest other considerations that we should keep in mind?

  • Windows 7 FTP Connection Ignores File Type Associations

    - by Travis
    I have an FTP connection active through the Map Network Drive option in Windows 7 64-bit. When navigating the remote directory, I see no way to edit files. Windows is completely ignoring file-type associations and "opens" everything with my default browser. Is there any way that I can simply edit these files? I'm open to suggestions of other software as well, but from what I can see, NetDrive doesn't work with 64-bit.

  • How can I use the "Windows Live Call Button" on my headphone to answer a call with Skype?

    - by Gnoupi
    Webcams and headphones from Microsoft (like for example the LifeChat ZX-6000, in my case) have a button which can be used only with Windows Live Messenger, to answer a call. There is no option provided to configure it so that it would launch a program, or work in another communicator, in the given drivers. Is there a way to make it work with Skype, so that I can answer a call by pressing this button? Maybe there are other drivers?

  • How do I prevent ConEmu auto-attaching to every single cmd.exe?

    - by naxa
    I don't want ConEmu to attach to every cmd I open, but this is how it works now. I remember that I told ConEmu to do this, but I don't want it anymore. Maybe I just overlooked something, but I've read all the settings pages and I couldn't find an option to disable it. Am I missing something? How do I prevent ConEmu from attaching every single cmd.exe I open? My ConEmu version is 121109 x86, on winXPproSp3x86.

  • how to setup OpenSSH per-user authentication types?

    - by Seaweed
    Hi - I'd like to be able to have one set of users authenticating using public key auth and the other set to use username/password. Is this possible in OpenSSH on Linux? If so how do I go about it? Right now, I'm stuck with only having one option as far as I can see in /et/ssh/sshd_config - it's either PAM or PublicKey authentication...

  • Auto-detected mouse - disable 3rd button enumation

    - by viraptor
    I'd like to disable the 3rd button emulation in ubuntu 9.10. Normally, I'd just change the option in xorg.conf and it would go away - but how do I deal with an autodetected mouse? For example, I've got a mouse I connect to USB and it has the emulation enabled by default. How do I change it in that case?

  • Update MS Windows XP via batch script

    - by oshirowanen
    Is it possible to update WXP using a batch script? Basically, I would like to run a batch script, which installs all important updates in the background accepting any dialog boxes which need user interaction. EDIT 1: I know I can enable the "Automatically download and install" option to do this, but I have about 100 computers to do, so it would be nice if it can be done via a batch file. That way, I can use the software we already have to run a batch file on all computers with a single click.

  • Is it possible to copy a set of files, but automatically skip if file already exists?

    - by awe
    I know that the copy command has an option to automatically replace a file if it already exists, but I want to know if it is a way to copy the files only if they not already exist (/Y). I do not know the actual file names in the batch code, as I copy from the source using wildcards in the copy command: copy *.zip c:\destination The reason I want this instead of automatic overwrite is that the files are large, and to skip existing would save a lot of execution time.

  • Lazarus Form Recovery for Safari?

    - by Cawas
    I use Lazarus a lot on Chrome and FireFox. Well, not a lot, but it's great for crashing when you're writing something online in a form that doesn't automatically save what you're writing. Plus, this should be default in every browser ANYway, and not built-in any web site (such as gmail). So, is there any such option for Safari? Does Saft do that? Just by looking at the home page, it seems to me like bloatware to Safari 4.

  • Can't find advanced settings on my SMC router

    - by homestead
    Trying to change my SMC router's WAn setting to use opendns dns. Following the instructions: https://store.opendns.com/setup/device/smc I don't see advanced settings anywhere, and none of the menu or menu options have WAN and dns relation options. Could my ISP (who provided the router) blocked that option?

  • FC SAN network high-error rate simulation

    - by Wieslaw Herr
    Is there a way to simulate a malfunctioning device or a faulty cable in a FC SAN network? edit: I know shutting down a port on a switch is an option, I'd like to simulate high error rates though. In an ethernet network it would be a simple case of adding a transparent bridge that discards a given percent of the packets, but I have absolutely no idea how to tackle that in an Fibre Channel environment...

  • Unable to boot from LiveCD/USB and even Super Grub Disk!

    - by Reuben L.
    Hi all, I'm in a fix. Basically this morning, I decided to format my Win7 as it was getting really slow and I did so with no problems. I also have a Linux Mint OS on dual boot. Since I was springcleaning my windows partition, I decided it was a good idea to do the same to my linux partition. I downloaded the latest version of Linux Mint (Julia) and burned the LiveCD. Now here is where the problem lies, when I restarted Windows and chose to boot from the LiveCD, it didn't work. No joke. There was just a little underscore blinking for a long time before it went back to GRUB which prompted me to select an OS to boot. However, when I went into my old Linux Mint OS and restarted the machine, the LiveCD worked... to a certain extent. It would load and look as though it was ready to install Linux Mint 10 but the moment it got to the option screen, the whole screen turned into a checkered and jumbled mess. At this point I thought it was the LiveCD or the .iso file. I had an Ubuntu LiveUSB for recovery purposes and I tried that. The exact same thing happened. Can't boot the LiveUSB if I restarted from Windows, but works when I reboot from Linux. BUT still the same checkered screen that doesnt respond. Did a bit of googling and reckoned it might be something wrong with my GRUB. Did some updating and didnt make a difference. Then I tried the Super Grub Disk and STUPIDLY uninstalled GRUB. (Note that booting to SGD had the exact same problem - can't be done if I rebooted from Windows). Now I can't access my Linux Mint 9 cos the the bootup screen (mbr) only has Windows 7 as an option. Remember me mentioning that I can't boot from any CD/USB/recovery CD when I reboot from Windows? And now that I can't access Linux, there's no way for me to do any form of recovery! I've tried using the command prompt utility at startup recovery but to no avail. Anyone can help me with this?

  • R2 live migration between Opteron 8354 and 2435

    - by Safin09
    As per title, will the processor compatibility option allow a live migrate between an AMD Opeteron 2435 (dual proc, hex core) and an AMD Opteron 8354 (quad proc, quad core)? We are out of capacity and wish to use a newer dual socket server rather than an older (yet much more expensive) quad socket server in our cluster.

  • How can I disable the css {position:fixed} side-bar on Slashdot?

    - by Tom
    When I look at a story on Slashdot, I see a side-bar that sits constantly in the upper-left corner. Every time I open a story, I have to click on the "slash" sign in its upper-right corner. How can I disable it, so it will always have css position absolute, relative or static? Is there an option for it? Because I find it is slowing my browser down when I am scrolling the page. Thank you, Tom
